Referring t0 the ili'aii'ings, the numeral 1 indicates the brake shaftwhich inonni'ecl able hearings 2 and 3 fixed by means of lFILClZGlE inconvenient part of the 7 m earing 2 engages the shall "receiveancl COVQIthe upper end of the shaft and the ratchet Wheel 7. lhe casing 9 has aheaping 10 formed 111 its upper horizontal wall adapted in receive theupper tin'necl encl' ll of the shaft 1, a bme the squared portion 3; Thelower Wall of the casing is cut away The usual feet eperatcd pawl l to,forma bearing I2 concentnc with the 'bearing. v10, of larger diameter.and adapted Mamas w grpv 13 ormed upon an 14 upstanding: fromthebearingt. 'The'beiiring 12 is madef of sufficient diameter to permitpassage of the ratchet Ttliflthfough in assembling-0r separating theparts.

A suitable locking lor its equivalent as 15 extends through the'wall'ofthe hearing 3 into engagement 1 with, an annular groove 16, formed inthe shaft 1 for'retaining the shaftagainstendwisemovement said bearing.'.-A similar locking screw as 17 extends through the wall: of thebearing 10 into an annular groove 18, formed'in the upper end 11 of theshaft 1, for retaining the handle againstdisconnection from the upperend of the shaft. t Mounted upon a pivot '19 extending verticallythrough the casing 9 -is a pawl 20 having its free end 21 disposed forengaging the teeth 22 of the ratchet YLZ'A spring. pressed rod 23 hasone of its ends} engaging in a suitable pocket 24: formed upon the outerface of the pawl .20 Thespring 25-as for said rod surrounds the andhasone of. .its endsresting against a washer-26"' which i .in turn restsagainst'a web' 2 7 formed in the handle 8,"andits other end montactingwith ..a collar 27 on'the rod; '23 adjacent the pawl 20. The pressure ofsaid spring against the collar 27 serves 'toiorce the rod yieldinglyagainst the pawl ,for'pressing said pawl constantly toward the ratchet7.

The handle 8 issubstantially U-shap'e in cross section having its openside disposed downwardly, and the rib 27 follows the shape of theinterior of the handle,leaving a suflicient opening for the passage ofthe end of the rod 23 therethrough; and suitable shoulders'as 28-28 areformed. upon the opposite ends of said rib 27 for maintaining the washer26 against displacement.

Formed upon the extension 14- of the bearing 3, above the bearingportion, 13 and within the hollow of the casing 9; is ,a fixed lateralfinger or stop 29. The pawLQO is formed with a shoulder or extension 30sodisposed with relation to the stop 29 as to contact with said stopwhen the lever orhandle 8 is moved or rotated into its normal positionof rest for lifting the free or ratchet engagingend 21 of the pawl 20positively from engagement with, and outof the path of, the teeth of theratchet 7. V A retaining latch 31 carried on a suitable base 32 fixed toa convenient portion of the car structure is disposedfor engaging one ofthe legs of the U-shaped handle "8; see Fig.

Further movement of the leverwill rotate. the ratchet, and with it the shaft 1,. for tightening thebrakes. If one oscillation is insufii "is operated to maintain the shaftin its partly rotated position and the lever 8 is returned to orjnearits original position and again oscillated. .When the brakes" arefinally set the shaft may 'be retained the foot awl 4: andthe lever 8may be returned to it normal position and allowedto remain until-againrequired for setting the brakes. When the brake handle is in its normalposition, the operation of releasing thebrakes does not efl ect theposition of the lever. To release the brakes the foot pawl 4 isdisengaged from the ratchet 5 and the ,shaft 1 will rotate freely, theteeth of ratchet T passing clear of the pawl 20. From this disclosure itis obviously'within the skill of the mechanic to rearrangethe parts sothat the pawl and ratchet will operate in the op Fig. 6 is a detail,view showing the parts arranged to drive the shaft '1 in a direction thereversal of the drive it is necessary tllat a pawl 20? including ashoulder 30 sub} member the parts are capable of being as While theinvention is-he're' described as :being adapted disposed brake shaftprojecting downwardly j through thefloor of the car platform it willvplicable to a horizontally or otherwise disposed brake shaft.
